Radiation imaging system and storage medium

Abstract

A radiation imaging system includes a hardware processor. The hardware processor calculates an exposure index representative value of a radiation image based on the radiation image including a plurality of frame images. The hardware processor is capable of setting a target value of an exposure index differently for each imaging mode.

What is claimed is: 
     
       1. A radiation imaging system comprising:
 a controller comprising a hardware processor; and 
 a storage, 
 wherein the hardware processor, under control of a program stored in the storage, performs processes comprising:
 calculating a radiation dose applied when performing an imaging process that obtains a radiation image including a plurality of frame images, the radiation dose corresponding to a cumulative dose amount of all imaged frames in the plurality of frame images, and the radiation dose being calculated before or after the imaging process based on a dose index and a number of pulses, 
 
 wherein the dose index is calculated from at least one of (i) an imaging condition is applied when the imaging process is performed and which is received from a radiation generating apparatus, and (ii) distance information showing a distance to a subject, and 
 wherein the number of pulses represents a number of times that the radiation generating apparatus generates radiation in a pulsed state to obtain the frame images when the imaging process is performed. 
 
     
     
       2. A non-transitory computer-readable storage medium storing a program thereon, the program being executable to control a computer to perform processes comprising:
 calculating a radiation dose applied when performing an imaging process that obtains a radiation image including a plurality of frame images, the radiation dose being equivalent to a cumulative dose amount of all of the frame images that are imaged, and the radiation dose being calculated before or after the imaging process based on a dose index and a number of pulses, 
 wherein the dose index is calculated from at least one of (i) an imaging condition applied when the imaging process is performed and which is received from a radiation generating apparatus, and (ii) distance information showing a distance to a subject, and 
 wherein the number of pulses represents a number of times that the radiation generating apparatus generates radiation in a pulsed state to obtain the frame images when the imaging process is performed.
